St Gregory the Theologian

For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens; ²⁷Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people’s: for this he did once, when he offered up himself. ²⁸For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore.

¹Now of the things which we have spoken this is the sum: We have such an high priest, who is set on the right hand of the throne of the Majesty in the heavens; ²A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man.

I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture. ¹⁰The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly. ¹¹I am the good shepherd: the good shepherd giveth his life for the sheep. ¹²But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep. ¹³The hireling fleeth, because he is an hireling, and careth not for the sheep. ¹⁴I am the good shepherd, and know my sheep, and am known of mine. ¹⁵As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep. ¹⁶And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
